Permafrost
Arctic coasts are characterized by sea ice, permafrost and ground ice. This makes them particularly vulnerable to the effects of climate change, which is already accelerating rapid coastal

According to estimates, Alaska's thawing permafrost soils cost the USA several 100 million dollars every decade – primarily because airports, roads, pipelines and settlements require relocation

Coastal erosion in the Arctic
The thawing and erosion of Arctic permafrost coasts has dramatically increased in the past years and the sea is now consuming more than 20 meters of land per year at some

climbing temperatures. In addition, the rivers are carrying large amounts of sediment from thawing permafrost. How the Arctic Ocean will react to such changes is a very big question, which is concerning scientists

Lakes in the northernmost latitudes are widely considered to be a significant source of the greenhouse gas methane. In order to improve currently available climate-change projection models
